72 duster steering column swap

I don't think you'll have any problems mixing and matching parts but you'll be left with a shift tube inside the column with an unused lever in the engine compartment. It's really not that much work to just swap the entire columns. Disconnect the column electrical harness and shift linkage, unbolt it from under the dash and at the floor, drive out the roll pin at the steering coupler and remove.

I have pics here of converting and assembling a "floor shift" column if it's helpful: http://70duster440.com/interior.html
